Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.
Answer:
It is difficult to avoid a tsunami due to it being such a large volume of water that is capable of destroying a large amount of land.
Explanation:
However, even though it is difficult to avoid a tsunami, as they are extremely difficult to predict, there are ways where one can begin to prepare before it hits. One of the ways you can do this is getting to a higher ground far away from inland, avoiding downed power lines, and steering clear of buildings or bridges where large, heavy objects could fall during an aftershock.
Tsunamis are incredibly dangerous, since there is a great chance that if you get caught in one, you can drown. Since tsunamis have little to no warning when they arrive, it is always essential to be prepared when one strikes.
I hope this helped! :)
